Abstract
The utility model discloses a transmission line linear tower suspension ladder, which belongs to a maintenance tool for transmission lines. The utility model comprises a collapsible supporting rod which is uniformly distributed with collapsible foot rods, the collapsible supporting rod is provided with a force bearing and clamping device and an adjustable screw rod, and the lower part of the collapsible supporting rod is provided with a hook. After the utility model is arranged, the utility model is not needed to go up and down along the surface when the rod type composite insulator is inspected, and the utility model has the advantages of little consumption of physical energy for workers, convenient inspection and safety.
Description
The utility model relates to a kind of power transmission lines overhauling utensil, the multi-functional suspension ladder of lower wire on promptly a kind of transmission line tangent tower.
Because life of urban resident, industrial factories and miness, the vehicles, saline and alkaline soil and ocean influence air environmental pollution, the common porcelain insulator outer surface of overhead transmission line is polluted easily, cause insulativity to descend, finally lead to transmission line pollution flashover power outage.For addressing this problem, the bar type synthetic insulator is because its light and good pollution-proof performance has obtained application widely on power circuit; The bar type synthetic insulator, its insulated part is made up of epoxy resin and silicon rubber, collar plate shape silicon rubber sticks on the glass fabric of epoxy resin tube outer surface, it is except having good tension mechanical performance, outside the advantage such as antifouling property and easy transportation and installation, exist bending resistance bad mechanical property and surface silicon rubber easily to damage, problem such as tear and aging, checking, when changing the bar type synthetic insulator or going up the line conductor operation, mainly contain lower wire on the dual mode at present: the one, about insulated flexible ladder, there is the danger of falling of the big and high-altitude of staff's physical demands, the silicon rubber that also is not easy to check bar type composite insulation sub-surface in addition defective such as wear out; The 2nd, directly along the bar type synthetic insulator practice up and down, must forbid in this operation.
The purpose of this utility model provide the maintenance bar type composite insulation period of the day from 11 p.m. to 1 a.m not must along its surface directly about, staff's physical demands is little, checks transmission line tangent tower suspension ladder convenient, the protection personal safety.
The purpose of this utility model is achieved in that a kind of transmission line tangent tower suspension ladder, hanging ladder comprises collapsible support bar 1, be uniform-distribution with folding foot-driven lever 2 on the collapsible support bar 1, on collapsible support bar 1, be provided with load jig 3 and adjustable screw mandrel 4, be provided with suspension hook 5 in folding support bar 1 bottom.
The transmission line tangent tower suspension ladder that the utility model provides, owing to adopt folding post upper to be provided with the structure that load jig and adjustable screw mandrel, lower end are provided with suspension hook, hanging ladder is securely fixed between iron tower cross-arm and the transmission pressure, make things convenient for about the maintainer, reduced staff's physical demands and the danger of falling in the high-altitude takes place.
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is structure of the present utility model, scheme of installation.
The utility model adopts following structure: a kind of transmission line tangent tower suspension ladder, hanging ladder comprises collapsible support bar 1, be uniform-distribution with folding foot-driven lever 2 on the collapsible support bar 1, on collapsible support bar 1, be provided with load jig 3 and adjustable screw mandrel 4, be provided with suspension hook 5 in folding support bar 1 bottom.
When this device uses, the load jig 3 of folding support bar is installed on the electric power line pole tower cross-arm 6, the suspension hook 5 of lower end hooks transmission pressure 7, will fold support bar with adjustable screw mandrel 4 and fix, and operating personnel can be overhauled bar type synthetic insulator 8 up and down by foot-driven lever 2.After maintenance finishes, unclamp adjustable screw mandrel 4 and load jig 3, take off suspension hook 5, hanging ladder can be taken off from transmission pressure 7.Adopting collapsible support bar 1 and foot-driven lever 2 is for easy to carry.
